Around 5:30pm this afternoon I was down at the RTC 4th Street Station here in Reno waiting to catch the 3CC bus route home. It was pouring rain in torrents and all the gutters were filling up. Twenty five minutes later I exited the bus in front of Raley's on Keystone Avenue just up from W 7th Street. The puddles in the gutters were above the height of my shoes.
So during the time I was wading through these puddles, it occurred to me that it is not easy when it is raining or snowing, especially if either rain or snow is on the ground.
If you are driving anywhere that deep puddles of water are, do not go very fast. Water weighs 8.35 lbs per gallon. Deep puddles are obvious to say that if you drive too fast through the puddles, the water is going to slosh from side to side and up and down, and your car is going to lose control. Remember Newton's third law of motion: An action is an equal and opposite reaction.
I would say SUVs have an advantage to drive through puddles of water because their ground clearances are higher than economy cars. The Geo Metro has a very low ground clearance, for instance, so it would not be easy to drive this small a car through deep puddles of water.
